"WILLIAM PEMBLE,

CINDER-GUARD.

' application filed July 1,

To all whom it may concern: v

Be it'known that I, CHARLES W. KnNNoN, a citizen of the United States, residing at Tampa, in the county of Hillsborough and State of Florida, have invented certain new and useful Improvements in Cinder-Guards; and I do hereby declare that the following is afull, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7

The present invention relates to improvements in cinder guards for railway trains, and the primary object thereof is to provide a cinder guard attachable to the car between 'ad acent windows thereof and including a body portion or space adapted to catch the cinders and of cinders into the following car-window, and which further consists of a flue disposed in communication with the body portion of the guardand receiving the cinders therefrom, in which flue thereis a draft; induced by the movement of the train to cause the cinders to be sucked downwardly to a point well beneath the window ledge and to there discharge the cinders.

Another object of the invention resides in providing a cinder guard wherein the cind'ers will be caught and will be transmitted being apt to rebound over the sides of the guard and into the winand wherein deflectors areprovided in order to check any such rebounding movement of the cinders and to cause such cinders to pass on to a flue through which they are exhaustedto the atmosphere.

It is a further object of the invention to provide an improved cinder guard of a sun- .ple and inexpensive construction and one which will constitute an ornament to railway cars and the like.

. With the foregoing and other view, the invention will be more scribed hereinafter, and will be ticularly pointed out in the claims hereto.

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views,

with a portion of the screen removed and with parts shown insection;

Fig. 3 is a horizontal sectional view taken on the line 33 in Fig. 2; and

Fig. 4 is a fragmentary longitudinal sec tional view taken on the line 4 4 in Fig.

Referring more particularly to the drawings, l designates generally a railway car having adjacent windows 2 and 3, and 4 represents the panel between the windows.

In accordance with the present invention have mounted my improved guard in the panel 4 between the windows 2 and 3. It is assumed in Fig. 1 that the railway car is-traveling to the left.

In accordance with the invention I provide theguard with a body portion and a flue which are intercommunicating and which are bothpreferablyformed of sheet metal infthe same piece. (The rear wall 5 of the body portion extends diagonally with respect to the line of draft so that cinders striking the said wall will be guided toward the outer portion of the guard and caused to enter the flue '6 which is disposed at this point, and by which thecinders are exhausted to the atmosphere.

The flue 6 is made by coiling the sheet metal at the outer portion of the guard in a volute manner, thus forming a central chamber 7 communicating with the body portion by volute passage-8. The. extremity 9 of the sheet metal is folded over llpon itself for the sake ofstrengthand to constitute one wall of the internal chamber 7. The sheet metal is offset outwardly upon itself at the forward portion ofthejfiueto constitute an abutment 10 to which one end of the wire screen 11 may be attached. This abutment 10 also constitutes a stop for preventing cinders, which seek their way along the screen 11, from creeping over the flue and thus getting access to the windows.

The inner edge of the rear. wall 5 of the guard is indicated at 12'and is secured as by screws or other fastenings 13 to a strip 14 and to the window panel 4. The wire screen 11, which forms the front portion of the guard, can be made to extend at a right angle with respect to the car wall or at any other angle desired. The space between the screen 11 and the rear wall 5 is preferably divided by a number of partitions 15 into a succession of compartments one above another. The partitions 15 are provided with laterangle which verge'nt wings of that the cinders tend 'to gent relation at opposite sides of the partition. These wings spread out in such fashion that they deflect the cinders toward the rear wall 5 at an angle other than a right the cinders would ordinarily take werethe deflectors left out. This is of advantage as it directs the cinders on their rebound movement, if any, beneath the diadjacent deflectors so that the cinders are pocketed in this manner and prevented from further escape from the guard.

The flue is extended, as shown in Figs. 1 and 2, below the wall 5 and the other portionsof the guard, and it has an open outlet at its bot-tom which lies well below the window sills for the discharge of the cinders and other matter which may get into the guard. The discharge is at such a point will not be apt to fly upwardly under the force of the air currents developed as the train moves. The air passing beneath the lower discharge end of the flue will create a suction and a partial vacuum in the fluewhich will be relieved by the air through the screen 11 passing out of the volute channel 8 and down through the chamber 7. The cinders are thus drawn in fromall sides about the guard and effectively prevented from entering the window. A top 19 .is provided for the guard which also closes the upper end of the flue and prevents any induced draft at this point which would lift the cinders and discharge them above the window.

I It will be appreciated from the foregoing that a cinder guard constructed and mounted as herein disclosed, and operating in the manner described, will constitute an effective barrier against the entrance of cinders into railway car windows. It will also be obvious that the guard is of an inexpensive construction inasmuch as the major portion weight beneath the windows.

guard for receivmg thereof is constructed of light sheet metal readily bendable into the shape necessary to form the guard and being desirably of a light construction so as not to add substantial weight to the car.

The screen 11 will avoid large cinders from entering the guard as these latter will fall by gravlty downwardly over the face of the screen and fall by virtue of their An apron 20 is provided by extending the wall 5 downwardly in order to effectively check any of these large cinders after getting below the screen 11. The outer ends of the dedicated in 8, to lie close against the adjacent portion of the wall 6 of the flue in 7 order to reinforceand strengthen the guard generally.

It is obvious that various. changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims. a 1

WVhat is claimed is i 7' 1. An improved cinder guard comprising a body portion adapted to receive cinders, a screen over the body part, and a flue communicating with the body part and adapted to convey the cinders therefrom below the line of a car window, scribed. v

2. An improved cinder guard comprising a sheet metal body portion'having a rear wall diagonally disposed with respect to the line of draft and adapted to guide the cinders toward the outer portion of the guard, and a flue at such outer portion of the the cinders, being composed of a volute channelhaving walls of sheet metal, and a screen over the front portion of the guard, substantially as described. 7 ,7 7 r 3. A guard of the characterdescribed comprising a body portion, a number of partitions secured transversely in the body portion and dividing the same into a number of compartments, V-shapedz deflectors 7 carried by the outer edges of said partitions, and a flue connecting with the various compartments, substantiall .as described. 7
